I studied various pathways to achieving a carbon-neutral energy system in the United States across all sectors by 2050. We looked at how various inputs and constraints affect the kinds of technologies we would expect to see in use, with each set of inputs referred to as a “sensitivity.” I translated the constraints to numerical values we could run in our software. I also visualized many of these sensitivity results in the visualization software Tableau, which I then incorporated into the final presentation. I tackled other tasks such as calculating the carbon intensity of the main sensitivities, calculating and visualizing installed capacity and transmission costs state-by-state and nationally, visualizing the buildout of electric vehicles and charging stations, and researching web-design software. I gained a thorough understanding of Tableau and sharpened my skills in working remotely. I also have a much greater understanding of the scale and impact of the American energy system, and the importance of green technology in getting us to a carbon-neutral future. I would like to incorporate energy-systems research as a senior thesis topic, and possibly even pursue it in graduate school.
